SPECIFICATION forming part of Letters Patent No. 576,856, dated February 9, 1897.

Application filed September 28, 1896. Serial No. 607,211. (No modell) T0 @ZZ whom, it may concer/t:

Be it known that I, ALFRED KERN, a subject of the King of Prussia, Emperor of Germany, residing at Magdeburg, in the Kingdom of Prussia, German Empire, have invented certain neW and useful Improvements in Adj ustable Sewing-Wheels forDrilling-Machines, of which the following is a specification.

My invention relates to improvements in seeding-Wheels for grain-drills; and it consists in the novel features and combination of parts hereinafter described and claimed. A

Reference is had to the accompanying drawings, wherein the same parts are indicated by the same letters throughout the several views.

Figure l is a plan view of the seedbox and the seed-discharging device therein. Fig. 2 is a transverse vertical section taken on the line 2 2 of Fig. l, parts being broken away. Fig. 3 is a longitudinal vertical section taken on the line 3 3 of Fig. 4, the discharge-spout and the operating-shaft being shown in elevation. Fig. 4 is a transverse vertical section taken on the line 4 4 of Fig. 3 and looking to the right. Fig. 5 is a detail view in elevation of the ring or iiange shown in Fig. 6, and Fig. 6 is a view as seen from the left in Fig. 5. Fig. 7 is a detail side view of the feed-regulating plate and its bracket shown in Figs. S and 9, and Fig. 8 is a view looking to the right in Fig. 7. Fig. 9 is a side elevation of the curved feed-regulating plate shown in Fig. 10 connected thereto, and Fig. l0 is a side elevation of this attachment.

A represents the seedbox, having sides A and A2, in which the shaft B is j ournaled.

C is the seed-discharging wheel, having rim C and interior flange C2 at one side of said rim, as seen most clearly in Fig. 3. Three or more curved radial arms C3 connect the rim C of the wheel C With the hub C4. This hub is fixed upon the shaft B by any preferred means. The flange C2 of the wheel C is provided with a number of small perforations 0 the same diameter as the hubs C4 and D2 and are loosely mounted inside of the Walls A and A2 of the seedbox A.

Three strips F are bolted at their ends upon the collars E andE' and rest upon the hubs C4 and D2 between the arms on the respective hubs, and are bolted to the hub D2, which supports the ring or iange D, but are not bolted to the hub C4 of the seed-Wheel C.

Y A pulley or gear-Wheel H is keyed upon one end of the shaft B outside the feed-box and is driven by any suitable gear for rotating the said shaft. The opposite end of the shaft B projects outward from the side of the seedbox and is provided with a reduced screwthreaded end b. The adj usting-nut I engages the screw-threaded end b and is provided with a shoulder t', which abuts against the outer side of the box A. A pair of right-angle guides I hold this nut l against outward movement. By means of this nut I the shaft B may be adj usted longitudinally, carrying with it the wheel C, the flan ge C2 of which is thereby moved nearer to or farther from the ring or flange D, the latter being immovable longitudinally. A lock-nut I2 is provided for locking the adj usting-nut I in the desired position.

K represents a curved plate which lits over the inner edges of the anges C2 and D, thus forming an inclosed chamber, as shown at K0 in Fig. 4, at one side of the Wheel C, and is held rigidly in position by means of the bracket K', attached thereto and bolted or screwed to the inner Wall of the seedboX. This plate K has a short small spring la at its lower end, which serves as a guide for the seed.

M -represents another curved plate, which carries a hooked spring Im at its upper end adapted to engage over a lug or catch lo' on the plate K, and with a tapering lower end m', adapted to spring under the lower end of IOO the plate K for attaching the said plate M to the back of the plate K. This plate M is to be used where it is desired to reduce still further the size of the chamber K, through which the seed passes.

N represents a receiving hopper or funnel into which the seed is discharged over the upper end of the plate K from the chambeuKO, and this hopper or funnel has an outlet-pipe vz, through which the seed is discharged to the earth.

The operation of my device is as follows: The seed to be planted is put into the box A and the shaft B is rotated by means of the pulley Il, driven from any suitable source of power. The rotation of the shaft B causes the rotation of the wheel C and the ring or flange D. These parts rotate in the direction indicated by the arrows in Figs. 2 and 4f. The seed falls into the space between the flange C2 on the wheel C and the separate ring or iiange D and is carried upward through the chamber K0 (seen in Fig. 4f) and is discharged over the upper end of the curved stationary plate K into the funnel or hopper N, where it runs out through the discharge-tube n to the earth. The width of the space between the fianges C2 and D is regulated to suit the quantity and size of the seed to be planted by means of the nuts d2 and cl3 on the screws d' and the adjusting-nut I, as hereinbefore described.

Should it be desired to make the measuring-space K, through which the seed passes to be discharged7 smaller than it is possible to make it within the adj ustment'of the flanges C2 and D, a separate curved strip M (shown in Fig. 10) may be sprung over the back of the strip K, as shown in Fig. 9.

It will thus be seen thatmyseeding device may be Vadjusted to sow seeds of widely-varying size and in correspondingl y-varying quantities. V

I'Iaving thus described myinvention, what Ielaim, and desire to secure by Letters Patent of the United States, is-

1. In aseeding device,the combination with a seedbox of a shaft journaled therein; means for rotating said shaft; a wheel having wide fiat rim with an interior flange thereon rigidly mounted upon said shaft within said box, and having perforations through the said fiauge; Van annular ring or fiange mounted loosely upon said shaft, and fitting within the rim of said wheel and adapted to rotate therewith; guide-rods rigidly mounted on said annular ring and projecting through said perforations in said interior flange on said wheel; radial arms carried by a hub loosely mounted upon said shaft connected to the ends of three or more of said guide-rods and supportin'gsa'id annular ring; a curved plate Vsecured rigidly to the side of the box and fitting over the in neredges of said flanges, and forming a closed passage for `the seed at one side of the wheel; a hopper adapted to receive the seed from one end of said passages; and a discharging tube or outlet from the bottom of said hopper, substantially as described.
